Important ATG certificate for Wommelgem producer

Manufacturer and developer of synthetic resins in the construction industry Resiplast recently became the proud owner of an ATG certificate for its liquid-applied elastomeric membranes for bridge construction. "We now have an ATG for waterproof skirts on the drivable asphalt strips of bridges as well as for the directly travelled safety zone for pedestrians and cyclists," says product and marketing manager Bert Dendooven.

The self-developed POLYAC^®-system is a versatile system, ideal for such applications as waterproof skirt on bridges and liquid waterproofing with ride-on wear layer. For those two applications, Resiplast holds an ATG certificate. "Surely this certificate was a must for us," says Bert Dendooven. "It gives confidence to contractor and builder that the system to be installed is of high quality."

ATG and ETA

An ATG is awarded by the BUtgb, the only Belgian approval institute that issues technical approvals for building materials, products, systems and of installers. BCCA vzw (Belgian Construction Certification Association), founded in 1992 by technical control agency SECO and  the Scientific and Technical Center for Construction (STCB), in turn looks after the awarding of the certificates. "Anyone who wants to obtain an ATG for these applications does need to hold an ETA, a European technical approval. To get an ETA, you have to meet the conditions of an ETAG, the European Technical Approval Guideline that is prepared by EOTA, the European Organization for Technical Assessment," clarifies Bert
Dendooven. "For the liquid application for waterproofing, that involves the ETAG033. When you then hold the ETA, you still have to meet additional national conditions in force in Belgium, which are determined by the BUtgb."

The system, developed by Resiplast, recently obtained ATG certification.

Class A and B

In Belgium, a further distinction is made between an ATG Class A and Class B. Bert Dendooven: "Class A, in a nutshell, concerns the guaranteed waterproofing under poured asphalt or asphalt concrete, while Class B also implies the waterproofing of the directly traversable cycling and walking zone. With the POLYAC^®-system, we have an ATG in both Class A and B. Even before we obtained ATG certification, our product was known and respected. Standard Specifications 250 still says "or equivalent. Provided the necessary effort and persuasion, we could prove this before, but the ATG certification makes these additional efforts unnecessary."

That the ATG certification on the POLYAC^®-system is no laughing matter, as evidenced by the rapidly increasing number of projects. The bridge over the Dender in Hamme, six ring canal bridges in Bruges, the drawbridge in Oostkamp, the Genk-Zwartberg bridge and the Balgerhoeke bridge in Maldegem-Adegem are just a few examples of reference projects.    ν
